[R] Help with Hist

[Ivan Calandra]

Hi,

I think you should also give the upper extreme:

x <- c(rnorm(80)+10, 101:110, 2001:2010)
hist(x, breaks=c(0, 20, 40, 60, 80, 100, 200, 500))
Error in hist.default(x, breaks = c(0, 20, 40, 60, 80, 100, 200, 500)) :
   some 'x' not counted; maybe 'breaks' do not span range of 'x'
hist(x, breaks=c(0, 20, 40, 60, 80, 100, 200, 500, 2100))  ## which 
looks horrible, but works, up to you how to cut it

HTH,
Ivan
